یک تلفن هوشمند با بودجه بزرگ TP-Link سری بودجه C خود را با Neffos C9 ، دستگاهی با صفحه نمایش 5.99 اینچی و MediaTek SoC گسترش داده است. برای C9 انتظار عملکرد معجزه یا قابلیت دوربین را نداشته باشید ، زیرا این امر به سمت کسانی است که می خواهند یک تلفن هوشمند بزرگ و بدون حاشیه داشته باشند. در ادامه بخوانید تا بدانید که Neffos C9 در تست های ما چگونه عمل می کند و آیا می تواند در کنار معاصران خود ایستادگی کند.
TP-Link Neffos C9
TP-Link هشت تلفن هوشمند در سال 20 را تنها با نام تجاری Neffos منتشر کرد. یکی از این موارد Neffos C9 بود که اکنون راه خود را در دفاتر ما پیدا کرده است. بزرگترین نقطه فروش آن صفحه نمایش 5.99 اینچی IPS آن است که در 1440x720 با تراکم پیکسلی 269 DPI کار می کند. علاوه بر این ، TP-Link فقط 150 یورو (167 دلار) را برای Neffos C9 شارژ می کند ، که به یک باتری غیر منتظره بزرگ 388 میلی آمپر ساعت نیز مجهز شده است. Neffos C9 را با سایر تلفن های هوشمند با بودجه بزرگ مقایسه خواهیم کرد. دستگاه های مقایسه ما شامل Gigaset GS100 ، Motorola Moto G7 Play ، نوکیا 2.1 و Wiko View 2 Go هستند .
در ادامه بخوانید تا بدانید که چگونه این دستگاه پیشرفته MediaTek MT6739 در برابر دستگاه های مقایسه ما عمل می کند ، به ویژه با توجه به اینکه فقط 2 گیگابایت رم و 16 گیگابایت فلاش دارد. TP-Link قول می دهد که Neffos C9 از تشخیص چهره پشتیبانی می کند و می تواند زیبایی سلفی به نظر برسد ، اما ما با توجه به اینکه این یک وسیله بودجه است ، در مورد هردو شک داریم. آزمایشات ما نشان می دهد که ادعاهای واقعی TP-Link چقدر هستند.

TP-Link Neffos C9 را به عنوان نمایشگر FullView به بازار عرضه می کند. ما در اینجا با دستگاهی که نسبت صفحه نمایش به بدنه بالایی دارد ، سر و کار نداریم. C9 دارای صفحه نمایش های قابل ملاحظه ای است که در قسمت بالا و پایین 10 میلی متر (0.4 ~ در اینچ) و در طرفین 2 میلی متر (0.08 ~ in) اندازه گیری می شود. این دستگاه هیچ شکافی ندارد ، اما از مارک Neffos در حاشیه پایین برخوردار است. TP-Link همچنین با همان مارک و آرم شرکت ، پشتیبان اصلی را تزئین می کند ، فقط در صورت فراموش کردن چه وسیله ای را در دست دارید. C9 به رنگ روشن یا خاکستری تیره عرضه می شود. مورد دوم واحد بررسی ماست که دارای حاشیه های نمایشگر سیاه است. در مقابل ، TP-Link از ورق های سفید برای نسخه خاکستری روشن استفاده می کند.
The C9 measures 158.7 x 76.6 x 8.45 mm (~6.25 x 3 x 0.33 in) and weighs 170 g (~6 oz), which makes it larger than most of our comparison devices. Our review unit is surprisingly sturdy though, despite its metal effect plastic body and the unspecified glass protecting its display. TP-Link includes a case and a glass screen protector in the box, which should help improve the device’s durability.
Disappointingly, the battery in the C9 is not replaceable unlike predecessors such as the Neffos C5. Replacing the battery in the C9 requires disassembling the device, for which you will need specialist tools. You will also void your warranty if you do so.
Inexplicably, the rear-facing camera housing protrudes from the back case, which makes the C9 wobble about on flat surfaces. The raised housing, which has a silver lip around it, at least protects the camera glass from scratching. The included case hides the camera bump though, which stops the C9 from wobbling about. TP-Link has extended the silver finishing to the device’s fingerprint scanner too, giving the C9 a somewhat stylish look.

Connectivity
As mentioned earlier, TP-Link has equipped the C9 with a MediaTek MT6739 SoC, which integrates four ARM Cortex-A53 cores and a PowerVR GE8100 GPU. The former clocks up to 1.5 GHz across all cores, while the latter can reach a maximum of 570 MHz. There is also 16 GB of internal storage, of which about 11 GB is available upon first booting the device. The storage is rather slow and makes the UI feel sluggish, something which is not helped by the old SoC and only having 2 GB of RAM. The latter is common for budget devices though.
The C9 has a micro-USB port, which OEMs seem to be taking their time over replacing with USB Type-C for their budget smartphones. The device also has two SIM card slots along with one for microSD cards, meaning that you do not need to choose between dual-SIM functionality and microSD card expansion as other OEMs force people to do with the inclusion of hybrid SIM card slots. The device supports up to 128 GB microSD cards, but we could only format cards as external storage. Worse still, we could not store apps or data on any of our test microSD cards.
The C9 has a headphone jack, and a notification LED too, although it does not support NFC. Hence, you cannot use the device with services such as Google Pay, for example.
Software
At the time of testing TP-Link ships the C9 with NFUI 8.0, which it bases on Android 8.1 Oreo. Our review unit had February 2019 security patch updates installed by the end of April, for reference.
The default launcher in NFUI 8.0 has numerous options for customising how it operates. You can enable notification badges for individual app icons, change themes and use alternative icon packages. Oddly, the latter only works with TP-Link supplied icons and will not work with third-party icon packs. You must switch to an alternate launcher if you want to use those.
The UI also has a so-called eye protection mode, which reduces the blue light that the display emits during specific times of the day. There is an app cloner too, which allows you to have two installations of the same app. This is useful for apps such as WhatsApp, which only allows you to be signed into one account at a time by default. Cloning the app then means that you can be signed into WhatsApp with two accounts simultaneously.
The C9 also comes with plenty of bloatware pre-installed. Some apps such as Clean Master by Cheetah Mobile can be uninstalled, but others such as the TouchPal emoji keyboard cannot even be deactivated. The inability to remove or stop the latter from running is especially annoying since it regularly displays notifications and advertisements.
You can set up multiple accounts too should you wish to do so. We should also mention that TP-Link bases NFUI on Android Open Source Project (AOSP).

Communication & GPS
The C9 supports LTE Cat. 4 downloads and Cat. 5 uploads along with LTE bands 1, 3, 5, 7, 8 and 20. The device can also operate at up to IEEE 802.11 n Wi-Fi speeds, but it is a shame that TP-Link chose not to equip the device with a modem that supported the faster 802.11 ac standard, which you may have seen referred to as Wi-Fi 5 elsewhere. Our review unit maintained decent mobile network signal during our tests with it connected to the Vodafone network in Berlin.
The C9 averaged around 60 MBit/s in our iperf3 Client Wi-Fi tests, which we conducted with our reference Linksys EA8500 router. This will be fast enough for most internet connections, although the Gigaset GS100 offers closer to 100 MBit/s, which some residential Wi-Fi networks can now reach. However, all devices in our comparison table are well below the class average here.

Our review unit can locate us indoors, but only with an accuracy of up to five metres (~16 ft), and only when we are stood next to a window. The C9 takes a few seconds to find a satellite fix outdoors, but it is accurate to two metres (~6.6 ft) when it does find one.
However, we would recommend using a different device for turn-by-turn navigation as the C9 performed woefully in our sample bike ride. Our test device struggled to keep up with us when cycling in built-up areas and often took huge shortcuts to do so. The C9 plotted approximately a 9% shorter route than our trusty Garmin Edge 520, but we would not trust our review unit to give us accurate directions.

Telephone Functions & Call Quality
شماره گیر
Dialler
The C9 comes with a TP-Link phone app, which looks and functions like most alternatives. The app separates call history and contacts into two tabs, which are accessible at the top of the screen. There is a search functionality too, and a dedicated settings menu. You can also blacklist numbers among other useful features, although you must install a third-party app to use SIP services, which is disappointing.
Our test device has underwhelming call quality. We experienced no disturbing noises during our test calls, but the device could not always filter out background noise, for some reason. Moreover, wind noise masks our voice to the point where we sound unintelligible. We also occasionally had some calls that failed to connect despite having enough signal.
The included headphones filter out background noise better than the built-in microphone does, but voices sounded much duller than when making a call over the earpiece. We should also point out that the earpieces are made from hard plastic, which we found difficult to sit correctly in our ears. Ambient noise often passes through the gaps between our ears and the earbuds, which made it harder to listen to our call partner.
Using the loudspeaker is not a great experience either. The speaker loudly reproduced our call partner’s voice during our tests, but the microphone struggled to pick out our voice unless we were speaking from a quiet environment. Consequently, background and wind noise will obscure your voice if you are using the speakerphone.
The C9 technically supports voice over LTE (VoLTE). However, your carrier must provision the device on its network before the functionality will work.
Cameras
گرفتن عکس سلفی با Neffos C9
Taking a selfie with the Neffos C9
The C9 has two cameras, an 8 MP front-facing one and a 13 MP rear-facing one. The former takes passable selfies, but our test photos often look blurry. The edges of objects and fine structures are not always clearly separated either. Likewise, colours generally look too dark for our liking. The default camera app has a HDR mode and a beauty mode, the latter of which gives objects a slight blur to smooth out any uneven surfaces. Perhaps unsurprisingly, the C9 does not take beautiful selfies like TP-Link claimed it would.
The rear-facing camera does not do much better either, even in good ambient light. Objects in focus look slightly blurred, and most photos are overly washed out. The sensor has a propensity to underexpose scenes too. Colours look more vivid in macro shots, while fine lines and structures are separated well. The camera performed better in low-light conditions than we expected, but objects are still dominated by image noise and colours are strikingly inaccurate.
The default camera app lends its HDR and beauty modes also to the rear-facing camera. There is a professional mode too though, which contains options for granularly adjusting the exposure, focus, ISO, shutter speed, and white balance. You can also change the brightness, contrast, hue, and saturation should you wish to do so.
C9 فیلم های قابل قبولی را ضبط می کند ، اما فاقد هرگونه تثبیت کننده تصویر است. بر همین اساس ، فیلم ها غالبا مبهم به نظر می رسند مگر اینکه یک دست ثابت یا یک دست و پا داشته باشید. برنامه دوربین پیش فرض فقط سفارشی سازی هایی را برای رزولوشن ارائه می دهد ، که می توانید بین 480p ، 720p و 1080p تغییر دهید.

لوازم جانبی و گارانتی
TP-Link شامل چندین لوازم جانبی با C9 است. دستگاه تست ما با یک شارژر و یک کابل میکرو USB مربوطه ، یک کیس سیلی و همچنین یک جفت هدفون وارد بازار شد. این سازنده در حال حاضر هیچ لوازم جانبی خاص C9 را در وب سایت خود به فروش نمی رساند.
The C9 comes with 24 months limited manufacturer’s warranty. Please see our Guarantees, Return Policies and Warranties FAQ for country-specific information.
Input Devices & Operation
As we mentioned earlier, TP-Link pre-installs TouchPal as the default keyboard app. The app worked well during our tests and offers numerous customisation options, but it is disappointing that TP-Link prevents the app from being disabled or uninstalled. You can download and use a third-party keyboard app should you prefer, but TouchPal may still display notifications and adverts.
The touch screen in our review unit worked well during our tests. The pre-applied screen protector has a highly resistive finish though, which makes multi-finger gesture such as drag-and-drop movements difficult to perform. Removing the screen protector or replacing it with a third-party glass one would alleviate this issue.
The C9 has a fingerprint scanner, although it is not a particularly good one. Our review unit takes a moment or two to recognise our fingerprints if it does at all. Likewise, the facial recognition software is insecure. The device uses the front-facing camera for authentication that only captures a 2D image of your face, which makes it easy to spoof with a print-out, for example.

As we mentioned at the start of this review, the C9 has a 5.99-inch IPS display that operates at 720p. The one in our test device reached an average maximum brightness of 442 cd/m² according to X-Rite i1Pro 2 and is 86% evenly lit. These values put the C9 in the midfield of our comparison devices.
Unfortunately, the C9 uses pulse-width modulation (PWM) to adjust display brightness. This looks like flickering to human eyes and can cause health issues such as eye strain and headaches. The display in our test device flickers at 100 Hz when set to 20% brightness and below, which is low enough to cause adverse effects for those who are PWM sensitive.

Screen Flickering / PWM (Pulse-Width Modulation)
ℹTo dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 100 Hz ≤ 20 % brightness setting
The display backlight flickers at 100 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.
The frequency of 100 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.
In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9368 (minimum: 43 - maximum: 142900) Hz was measured.
The display also has a comparatively high black value, which we measure at 0.6 cd/m². The high black value results in an underwhelmingly low 745:1 contrast ratio and gives colours a grey haze. In short, colours will look more vibrant on our comparison devices than they do on the C9.
CalMAN analysis also shows that the display has a slight blue tint to it. We were able to reduce this by enabling the eye protection mode, which is freely adjustable. NFUI 8.0 does not include any colour modes or white balance options though.

Display Response Times
ℹDisplay response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 72 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.7 ms).
The C9 is easy to use outdoors, but bright sunlight will wash out the display. The glass has a highly reflective finish too, which can impede being able to read the screen.

The C9 has stable viewing angles thanks to its IPS panel. We experienced no brightness, colour or image distortions even at acute viewing angles. Hence, the display should remain readable from any angle, unless reflections block your view.

Performance
The C9 has typical hardware for an entry-level smartphone. Its MediaTek MT6739 SoC and 2 GB of RAM are just about powerful enough for the system to run smoothly, but you will notice some slowdowns and lags if you have several apps open at once. Its PowerVR GE8100 GPU and 16 GB of eMMC flash storage are not much to write home about either. In short, the C9 is only suitable for running simple applications or tasks such as Facebook, WhatsApp and browsing the internet.
Our review unit generally finished in the midfield of our comparison devices in synthetic benchmarks. The C9 typically scores more than what we would have expected from a MediaTek MT6739 powered device though.

The C9 also finished in the midfield of our AndroBench comparison table. The device has considerably slower storage than that of the Moto G7 Play but consistently beats the Gigaset GS100.
We typically test the speed of microSD card readers with our Toshiba Exceria Pro M501 reference card. However, our review unit could not read the card for some reason, which forced us to use a 32 GB Kingston card instead. Regardless, the reader in the C9 is woefully slow and achieved around 6x slower transfer speeds than our comparison devices did.

Games
The PowerVR GE8100 is powerful enough to play simple and older games, but that is about it. "Arena of Valor" runs smoothly, but complex titles such as "PUBG Mobile" are unplayable if you can even install them.
The touchscreen worked well throughout our gaming tests though. Unfortunately, the accelerometer takes a moment or two to react. Moreover, the pre-applied screen protector and its highly resistive finish quickly make performing swiping gestures a chore in games such as "Temple Run 2".

Speakers
The C9 does not have a dedicated speaker. Instead, it uses its earpiece, which gets unexpectedly loud. The audio produced by the earpiece sounds surprisingly balanced too. In short, the C9 is suited for occasionally listening to media content, but we would recommend using external speakers or headphones as these will deliver a better listening experience.
The 3.5 mm jack in our review unit grips headphone jacks tightly and outputs audio cleanly. We had no problems with Bluetooth audio either.

Power Consumption
Our tests certify that the C9 consumes at least 1.5 W at idle and a maximum of 5.2 W under load. Our test unit consumes more than our comparison devices overall, but slightly less than what we would have expected from a MediaTek MT6739 powered device.
TP-Link includes a 5-W charger in the box. The charger takes about three and a half hours to fully recharge our test device. It is only just about powerful enough to recharge the C9 under load too; we would have preferred TP-Link to have included a more powerful charger.

بررسی گوشی هوشمند TP-Link Neffos C9. حسن نیت دستگاه تست Cyberport.
TP-Link Neffos C9 یک تلفن هوشمند کنجکاوی بودجه است. صفحه نمایش بزرگ و سخت افزار منسوخ آن هنوز هم آن را به اندازه کافی مناسب برای برنامه های روزمره و کارهایی مانند استفاده از رسانه های اجتماعی و مرور اینترنت می کند. با این حال ، واحد بررسی ما مرتباً نسبت به معاصران خود تنبل تر عمل می کند ، و از لحاظ عمر باتری نسبتاً کوتاه به خود نیز کمکی نمی کند.
TP-Link Neffos C9 برای کسانی که بعد از یک تلفن هوشمند با بودجه دارای نمایشگر بزرگ هستند ، جذاب خواهد بود. با این حال ، شما باید با عملکرد بیهوده و عمر باتری غیرقابل تصور خود را تنظیم کنید.
امکان نصب دو سیم کارت و یک کارت حافظه microSD به طور هم زمان چیزی است که همه دستگاه های بودجه آن را ارائه نمی دهند ، اما این یک نکته کوچک به علاوه است. خلاصه اینکه Neffos C9 خود را از سایر تلفن های هوشمند بودجه متمایز نمی کند. خیلی خوب عمل نمی کند و در بسیاری از مناطق ناامید کننده است.
